REVOLVING PICTURE-EXHIBITOR.

SPECIFICATION forming part of Letters Patent No. 281,914, dated July 24, 1883.

Application filed January 29, 1883. (Model.)

To aZZ whom it may concern Be it known that I, ANDREW NELsoN, of Moline, Illinois, have invented certain new and useful Improvements in Revolving Pieture-Exhibitors, of which the following is a specification.

My invention relates to an improvement in revolving picture-exhibitors; and it consists in the combination of a suitable holder which is hung upon journals, so as to be readily revolved, and which is divided at its center, by means of a partition, into two compartments, with suitable springs which are connected to the partition, and suitable frames in whi ch the pictures are held, as will be more fully described hereinafter.

The object of my invention is to provide a revolving picture-holder, in which the pictures are placed in suitable sliding frames, which are separated in sets from each other by means of a partition, and which frames are so arranged that the upper one only moves after the spring has been depressed, so as to let it pass from the upper into the lower part of the revolving frame. v

Figure 1 is a front elevation of a revolving picture-exhibitor which embodies my invention. Fig. 2 is a similar view, with the front side or cover removed. Fig. 3 is a vertical section of the same. Fig. 4 is a vertical cross section taken at right angles to Fig. 3.

A represents my revolving pictureframe holder, which is provided with the journals (2, which pass through the frame or standards F, as shown. The other ends of these journals are provided with handles, by means of which. the exhibitor may be freely revolved, so as to exhibit the pictures. This holder is composed of the end pieces, D, which are attached to the side pieces, E, by means of suitable set-screws, cl. The two sides or fronts C of the holder are provided with glass in the usual manner,

through the side of the case, is attached a knob, J, against which pressure is applied to depress the spring H whenever it is desired to change the pictures so as to bring a new one into sight. These springs are so formed as to press constantly outward against the inner side of the glass in each cover 0, and in this manner project directly across the space through which the outer picture moves when it drops from the upper into the lower part of the frame. When pressure is applied to the knob upon the end' of either one of these springs, the spring and the plate connected thereto are forced backward into the recess formed in the edge of the partition made to re ceive it.

The photographs or pictures are placed in pairs in suitable metallic frames, 0, in the usual manner. These metallic picture frames or holders remain in position when the holder A ismade to revolve; but as soon as the springs are forced inward the top picture-frame im mediately drops down into the lower compartment, and thus brings a new one into view in the top of the holder A. The holder hasthen to be revolved before another picture-frame will drop, and then after the holder has been revolved the top picture-frame upon the op posite side drops when the spring. is depressed.

It will be seen in the construction above described that the springs which support the top picture-frame in position are recessed in the edges of the partition, and that the top picture-frame only drops when the spring is operated.

Having thus described my invention, I claim In a revolving pi eture-exbibitor, the combination of a revolving holder provided with a partition, G, at its center, with springs that support the upper picture-frames in position. and prevent the frames from dropping after the holder has been revolved until the spring has been forced inward, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

ANDREW NELSON.
